Abstract

Potatoes (Solanum tuberosum L.) play a vital role in ensuring global food security. Population growth, market demand, and the need for high-quality crop yields have driven the adoption of efficient technologies to identify somaclones with superior yield potential. This study was conducted with the primary objectives of identifying variance in potato morphological traits and yield, identifying relationships between measured traits, and selecting superior somaclones using multi-trait analysis. The experiment was conducted in Pangalengan, West Java, Indonesia, using a randomized block design with three replications. The analysis results showed significant differences among somaclones for all observed traits. The correlation analysis showed that tuber weight per plot (yield) had a significant positive correlation with various growth parameters and yield components. The increase in tuber weight per plot was in line with the increase in economic tuber weight, number of economic tubers, stem diameter, and plant height. In addition, leaf dimensions, including leaf length and width, also contributed significantly to the achievement of tuber weight per plot in each observation area unit. Furthermore, the Multi-Trait Genotype–Ideotype Distance Index (MGIDI) analysis proved successful in identifying three superior potato somaclones, namely G3, G4, and G7, with G7 being the most superior somaclone. The achieved selection accuracy was very high (86.4%), with heritability values ranging from 76.1% to 94.9%. Selected somaclones can be used for further potato breeding programs.
